SPECIFICATION forming part of Letters Patent No. 588,434, dated August1'7, 1 897. ApplicationfiledSeptember28,1896. Serial No. 607,150. (Nomodel.)

To all whom it may concern:

Be it known that I, WARREN B. HOWE, of Chicago, in thecounty of' Cookand State of Illinois, have invented certain new and useful Improvementsin Pasting-Machines; and

I do hereby declare that the following is a full, clear, andexactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

This invention relates to improvements in machines intended forfastening together by adhesive materials the blanks or parts of paper orstrawboard boxes or cartons; and the object of the invention is toenable the work of supplying adhesivematerial and the placing togetherof the blanks to be carried on with rapidity and with perfect accuracyin the finished work.

The invention consists in the matters hereinafter described, and pointedoutin the ap-' pended claims.

The machine herein shown embraces as its main or principal features atubular blankholder, which acts as a support or guide for the blanks atthe time the adhesive material is being applied thereto and to hold theparts of the box in proper relative position While drying, and apaste-applying device movable periodically into contact with the blanksresting in the tubular holder and acting to apply adhesivematerial tothe blanks asthe latter are placed successively in the holder by hand.

A machine embodying my invention is ap plicable in the manufacture ofboxes of any kind which are capable of being folded flat at the time thepaste is applied, the same being more especially adapted for use in themaking of what are known as knockdown boxes. The machine herein shownis, however, more especially designed for the making of cartons, such asare used for packing candy and other articles inbarrels or-pails andwhich consist of a plurality of sectorshaped cells or compartmentsformed by radial walls connected at their outer ends by equal andsimilar sections adapted to fold upon their lines of juncture With eachother simultaneously with the folding together of of the adjustableguides in the blank-holder,

showing the arrangement of the spring-retarding arms. Fig. is ahorizontal sectional View of theparts shown in Fig. 3, taken on the line4 4. thereof. Fig. 5 is a planview of the machine with thepower-applying mechanism and a portion of the link broken away. Fig. 6is a vertical section taken through the paste receptacle and reservoirand through the paste-carrier on the line 6 6 of Fig. 5.. Fig. 7 is avertical section of the mechanism, taken on the line 7 7 of Fig. 5. Fig.8 is a detached sectional view of the compressible link with its springremoved. Fig. 9 is a horizontal sectional view of the blank-holder,paste-carrier, and paste receptacle and reservoir on the line 9 9 ofFig. 5 and showing the paste-carrier in different positions. Fig. 10 isa view of the carton after the paste has been applied by the machinewith some of the compartments opened. Fig. ll is avieW similar to Fig.2, showing a portion of the machine, but with the adjustable plates ofthe paste-carrier and of the blank-holder arranged for pasting adifferent-shaped box.

The machineis shown as mounted on a table consisting of a horizontal topA and four legs attached thereto. A rectangular portion A extendslaterally from the table-top and supports a standard A in which is journaled a shaft B, which has rigidly fastened to its right-hand end anordinary belt-Wheel B and on its left-hand end a gear-pinion B whichmeshes with a gear-wheel O, rigidly and centrally fastened to a shaft 0,which is journaled at its right-hand end in a bearingin the standard Adirectly above the bearing for the shaft B. The shaft 0 is alsojournaled in a bearing in the curved stand ardA projecting up wardly andforwardly from the rear of the table A, and carries at its left-hand enda crank C to which is pivoted a connecting rod or link, shown asconsisting of two parts D D, through which motion is transmitted to aswinging frame E, to which is attached the paste-carriers F, by whichpaste is transferred from a paste-receptacle H to the blanks held in atubular blank-holder K. The said link, as shown, is made yielding orcompressible lengthwise, and for this purpose consists of the screwthreaded eyebolt D, which can slide to a limited extent in the tubularsocket D, which is pivoted at its forward end between two cars E on theswinging frame E. The socket D has a slot D in its upper surface, inwhich plays a pin D projecting upwardly from the forward end of the boltD, as clearly shown in Figs. 7 and S. A strong helically-coiled spring Dsurrounding the bolt D, is confined between the rear end of the socket Dand a nut D on the screwthreaded portion of the bolt D, which is held inplace by a lock-nut D The frame E, as seen in Fig. 5, is rectangular inshape and is carried by parallel arms E pivoted thereto and projectingupwardly from the ends of a pair of parallel rock-shafts E, which aremounted on bearings carried by the lugs A on the table. Theserock-shafts E might be journaled directly in the lugs, but I prefer tohave bearing-cavities in their ends,with which cooperate the ends (shownas conical) of bolts E inserted through the lugs A and held by thelock-nuts at any desired adjustment. It will be readily seen from thisconstruction that when the shaft C is rotated, the bolt D and the socketD ordinarily operate as a rigid link, and the frame E will be carriedback and forth from the two extreme positions shown in Figs. 8 and 9.

The forward portion of the frame E has rigidly fastened to the underside or integral therewith, as shown, the rectangular plate E containingthe parallel longitudinal slots E (best shown in Fig. 5,) by which thepastecarriers are secured to said frame. These paste-carriers, as seenin Figs. 5 and (3, consist of plates F, which are rectangular in planview, but of L shape in cross-sectional form, and in thedownwardly-projecting portion or flanges of the plates are fastened twoparallel rows of paste-applying pins F. Said pins are .brought intocontact with or have their ends immersed in the adhesive material in thepaste-receptacle at each backward movement of the paste-carriers and arebrought into contact with or pressed against the blanks, so as todeposit on the blank the material which adheres to their ends, somewhatas ink is deposited from type in printing.

The proper angular adjustment of the plates F on the frame E is elfectedas desired by screws F which pass through the slots E and enter the topof the plates F, so as to hold them in any desired position. In themachine here illustrated it is desired to have the paste applied on theportions of the box where the laps G of one portion come against theends of the .radial parts G of the adjacent portion, as shown in Fig.10. As the portions or blanks which form the carton are not rectangular,but are irregular in their shape, as shown in Fig. 5, the twobrushplates F are set at an angle to each other, as seen in said figureand as more clearly shown by the spots upon the folded boxes, showingwhere the paste has been applied.

The pins F at each rearward movement of the frame E are thrust into thepaste-receptacle H a fixed dept-h. As it is desirable that the pinsshall always take up the same quantity of paste, it is necessary thatthe pastereceptaele always be filled to a uniform depth, and thiscondition is attained by the following mechanism:

The paste-receptacle H is located above the level of the paste-reservoirH said receptacle, as herein shown, being mounted upon posts H,restingupon the bottom of the pastereservoir, which has the form of a shallowrectangulartank. Said reservoir, as shown in Fig. 5, rests by means ofposts H upon the top of the table. Journaled in the righthand end of thereservoir 11 is a horizontal shaft 11*, which has secured to itsright-hand end abelt-wheel 11, through which said shaft is driven bymeans of a belt J from a similar belt-wheel C fastened on the shaft 0.To the left-hand or inner end of the shaft H is attached a disk H,thelower portion of which is immersed in the paste in the reservoir II",as shown in Fig. 6. The paste-receptacle H 'is rectangular in shape, asseen from above,

except that it has a rectangular offset portion H at the rear portion ofits right-hand end, said offset portion bearing at its end against aportion of one side of the disk H It results from this construction thatas the disk H is rotated and passes into the paste it will carry up thepaste which adheres to it, and the adhering paste will be scraped off bythe edge of the receptacle II and will flow into the said receptacleasthe rotation continues, thus keeping the receptacle constantly full tooverflowing, the disk H carryingupwardly and depositing the paste fasterthan it is removed by the paste-carrier.

To the forward end of the table A is secured the blank-holder K, whichis substantially rectangular in plan view and contains within it adjustable guide bars or strips, whereby its bearing-surfaces, which engagethe edges of the blanks, may be shaped so as to accommodate blanks ofany desired form. The vertical rear wall K of thetubular holder has across-section of the shape shown in Fig. 5 and carries two guide-strips,the first of which, L, is not adjustable, but is substantially rigidwith the right-hand side of the rear wall K. The second strip L on saidwall K is adjustable by means of set-screws or bolts L (shown in dottedlines in Fig. 5,) passing through the slots K in the rear wall K andentering said st-rip L. This strip L is shown as adjusted to difierentpositions in .Figs. 2 and 11.

The right-hand side wall K has no adjustable strips; but a raised stripK furnishes a smooth flat surface against which the edges of the blanksrest and by which they are guided on this side, as shown in Fig. 5. Theleft-hand side wall K has mounted thereon a guide-strip L of thecross-sectional form shown in Fig. 5 and adjustable inwardly andoutwardly by means of set-screws L which engage screw-threaded holestherein and pass through screw-threaded lugs in the wall K The frontwall K has mounted therein a supplemental wall K, having a cross-sectionas shown in Fig. 5 and adjustable backwardly and forwardly by means ofthumb-nuts K on I screw-threaded bolts K which are fastened to the rightand left hand ends of the wall K The supplemental wall K has at itsrighthand end a raised portion or strip K furnishing a flatguide-surface for the blanks, and at its center is an adjustable strip Lsimilar to the strip L, similarly mounted and adjusted and acting toguide the blanks, as shown in Fig. 5 It will be seen that bythisconstruction of the holder K, as hereinbefore described, I have obtaineda structure that guides the blanks of the shape illustrated through itwithout allowing any shifting from the position first assumed, and alsoone that is capable of being adjusted so as to accommodate blanks ofvery different shapes.

"To prevent the blanks from passing through the holder K without anyresistance and to yieldingly detain them at the bottom so that inoperation the holder will always be full and those at the top willremain in proper position for the action of the paste-carrier thereonand offer sufficient resistance to the pressure of the paste-applyingdevice to insure proper application of the paste thereto, I place in thelower end of the holder spring arms or detents M, adapted to standnormally in position to resist the downward movement of the lowermostblanks in the chute, but

adapted to yield outwardly under downward a downward inclination intothe tubular holder. Each spring rests in avertical groove or recess m,adapted to receive its lower end when thrust outwardly.

The means shown for attaching the springs to the guides consist of slotsm, Fig. 3,

The blanks approach the lower end of the I holder K, and meet withconsiderable resistance to their further progress from thespringdetents, which is overcome by the weight of those above them andthe pressure of the paste-applying device acting thereon. As vthey arefinally forced out at the bottom, the lug M offering more resistancethan is experienced at any other side, the box is .released from thatside last, so that it falls always in one position, as shown in Fig. 9.

While I have herein called the device for I holding and guiding theblanks a tubular blank-holder, yet it is to be understood that theessential parts of such holder are the guides or guide-stripsthemselves, and the holder may be of skeleton form or consist of guidessupported in any suitable way and need not be tubular in the sense ofbeing a closed tube, and which latter form of holder is herein shownmerely as a matter of convenience in construction.

The carton, which the machine illustrated is more especially intended tomake, is shown in Fig. 10, the same consisting of a plurality of radialpartitions G G, each adjacent pair of which are connected by two arewalls G G flexibly joined to the radial walls and to each other at apoint midway between the radial walls, so that the cell formed by thetwo radial walls and the two are walls may be folded fiat by the outwardfolding of the arc walls on their lines of juncture and the bringingofthe radial walls into contact ,with each other, as clearly seen in Fig.10. The carton thus constructed is composed of a plurality of separatepieces, each of which forms one radial wall G and two are walls G2 G andwhich is provided at its ends with flaps G G forming extensions of theinner end of the radial wall and the extremity of the arc wall, so thatwhen the said flaps are pasted to the outer faces of the radial walls ofsimilar blanks a series of compartments will be formed, as clearly seenin said Fig. 10.

All 'of the compartments necessary to constitute a circular or segmentalcarton will be made by the use of like blanks, with the exception thatthe end compartment of the series will be finished by means of a fiatblank G equal in length to a radial wall only and which when the cartonis expanded will rest against the radial wall at the opposite endthereof, as clearly seen in dotted lines in said Fig. 10. The blanksforming the carton of the kind described are joined when in theircollapsed or folded position by applying the adhesive material to theflaps G G or to the marginal parts of the arc walls against which saidflaps rest and piling the blanks one upon another with their edgesaccurately in register. In thus piling the blanks the number used foreach carton is equal to the number of cells in the carton, and a singleblank to form the radial wall G is then applied to complete the final orterminal cell, when the carton will be finished in knockdown form andmay be readily expanded into its circular form. The construction of sucha carton is more fully explained in the prior patent granted to F. B.Davidson February 5, 1895,

In the operation of the machine the operator stands in front of it andhas in a convenient position a supply of the two kinds of blanks abovereferred to-namely, the blanks forming the walls G G and the shorterblank for forming the wall G These blanks will conveniently be placed onextensions A of the table, Fig. 5, which are located at either side ofthe front of the machine. Assuming the blank-holder K to be filled withpreviously pasted and folded blanks, or with a suitablyshaped fillingpiece or block to support the first blanks, the operator first takes ashort blank and lays it on top of the pile between the upper ends of theguide-strips K K, L, L, L and L The machine is then started and thepaste-carrier moved from the pastereceptacle into contact with theblanks, against the upper surface of which the pasteapplying pins arepressed, so as to leave an imprint of paste thereon,- the paste beingapplied in a line at either end of the blank. The action of thepaste-carrier serves also to press the entire pile of pasted blanksdownwardly a short distance through the guides. One of the longer blanksis then folded by the operator into the form shown in Fig. 10, the flapG being folded against the adjacent radial wall, while the flap G isleft in the same plane with the outer portion of the are wall, to whichit is attached. The folded blank is then placed in position on top ofthe pile between the guide-strips, thereby bringing the two flaps G andG3 against the pasted portions of the shorter blank. The blank is soplaced on the pile during the time the paste-carrier is moving towardthe pastereceptacle and returning therefrom, and in the subsequentadvance of the said paste-carrier the latter applies paste to the topsurface of the longer blank at the inner and outer margins of the radialwall thereof. A second long blank is then folded and placed on the firstlong blank, and these operations are re peated until the number ofblanks added to the pile equal the number of cells in the carton. Thecarton shown in the accompanying drawings, Fig. 10, is provided withfive of such cells, and consequently consists of five of the longer orfolded blanks and one short blank. After the carton has thus beencompleted a new carton is started by placing a short blank on top of thepile without permitting any paste to he applied to the last blank of thecompleted carton. This may be done by placing a folded blank and a shortblank together on the pile, or by interrupting the action of thepaste-carrier long enough to add the short blank, this being done bypressing down the treadle N, which throws the hook N upward intoposition to act on the rear cross-bar of the frame E, as seen in Fig. 2.The resistance offered to the descent of the lowermost pasted blank inthe pile,

combined with the weight of the superposed blanks and the pressure ofthe paste-carrier thereon in applying the paste, insures that thepaste-pots shall be kept closely pressed together until the partssufiiciently adhere or the paste is dried.

As above stated, the construction of the blank-holder permits the sameto be employed in the making of boxes of various shapes, and thepaste-carriers F being adjustable in position on the swinging frame thesame may be arranged to apply the adhesive material to any portion ofthe blanks desired, as made necessary by reason of the shape orconstruction of the box.

In Fig. 11 of the accompanying drawings I have shown the adjustableguides of the blank-holder and the paste-carriers as arranged to operateon a box-blank of rectangular form.

While my invention is herein shown as embodied in a machine adapted forpasting cartons of the particular form shown, yet it is to be understoodthat it may be applied to operate on boxes of different shapes and thatthe details of construction in the machine may be greatly modifiedwithout departure from the spirit of the invention.
